P-7811FX & NZXT Cryo? Be warned...

Just a heads up for anybody considering the NZXT Cryo to be used with the 7811FX...

When I first hooked it up, I ran both the DC and USB cables to the two left side USB ports and my 7811 wouldn't even boot... screen just stayed blank, no POST, no anything. I only tried it twice, but that is enough to know that something is wrong...

I then disconnected them and everything booted up fine. Once I was into XP I tried plugging in the cable and I get this:



When I plug the DC cable into the right side port, the fans start right up but it still throws the error. When I connect the USB to USB it throws the error briefly and then goes away once the fans speed up.

When I do the same under Vista I get the exact same results, but no errors are thrown. This really disappoints me because other than this issue I am really impressed with this thing.

Also there is nothing else connected when I am doing this. For those of you willing to use an external power source then this may not even be an issue, but you have been warned!

Peace

 

Interesting, never seen that before. I have an Antec cooler with 2 80mm fans and use a logitech wireless mouse & keyboard and have yet to run into any issues on the USB ports. I wonder how much your cooler draws compared to a normal one?

 

Yeah, it has 3x120mm fans so its a bit more than most I imagine.

I don't see any spec's on the NZXT website, and I don't feel like opening it up since I'm going to be returning it to Newegg.

I almost went for the Zalman ZM-NC2000B so I think I'll try that out next unless something else catches my eye...

 

Same cooler.. no issues.. at all. Works fine for me.

 

I have the USB to DC and USB to USB both plugged into the left USB ports, and have had no errors. In fact I also have a printer, external HDD, and ipod running out of the cryo's usbs, still no problems and I've been using it for a few weeks now.

A quick solution to your problem would be to just power your Cryo externally.

 

I have that issue, it just doesn't seem to happen all the time. Been running it for two days now without the issue...but this post isnt bs because ive seen behavior very much like this.

 

Tyreck, you stated in another thread that you had to plug your DC in on the right, and the USB on the left or you do not have enough power, and the fans don't come up to speed...

"Your USB-Power should be hooked into the right side USB, and your USB-USB should be hooked into one of the two left side ports. This should be enough power to run the fans constantly.

If you hook it up any other way, or without either of the two cables the fans won't turn."

AND

"I'm not sure what they are supposed to be by design, I'll tell you this much though. They don't all seem to be able to kick out the same power because the only configuration that would work is the one I stated above.

It might be something like having both plugged in on the left was splitting the power to far. Not really sure."

Sounds like the same issue to me... and the fans do turn, they just don't come up to speed, even on the lowest setting.

Also if you shut down your 7811, and plug both cords into the left side USB ports does your system boot up alright?

@Jakamo5 - I'm considering grabbing an external adapter, but I would rather not if possible... From the sound of it between myself, Tyreck, and Solitaryman you are the only one that actually has it working properly.

I haven't had any issues otherwise with any of my USB ports until I got this thing hooked up. Also when I plug it in with either cord to my desktop the Cryo fires right up...

 

Yeah I did say all that.. but I don't consider that an issue. It's not causing BSOD, and I can still use it as normal I just had to plug it in a certain way.

And also after further playing with the plugins it seems that if you turn the fan speed dial to high it works no matter where you plug it in, but you get significantly more airflow if you plug it in like I described.

I guess 'no issues' was to short.. my bad.

I also might just plug it into a DC source because I have a suspicion that it will increase airflow even further, but I haven't tested this at all to know for sure.

 

Oh I didn't mean any offense dude! Just making sure I understood how you got things working comparatively speaking.

I may just give in and order one of these, or take a ride to my local Radio Shack:

It does bother me that Jakamo5 seems to have no issues at all with using both left side ports...

I just tried it again using both left sides, and it will not boot. However if I place the DC on the right, and the USB on the left all is well.

I also noticed that with the laptop up higher having the cord stick out on the right really isn't that big of a deal. I really am impressed otherwise with this thing! I just loaded up WoW and let it run for a good 10+ minutes and so far my GPU load temps have dropped 12-15C!

It also blows a nice breeze out the right hand side onto my mouse hand, which is surprisingly refreshing lol.

Maybe I'll keep this thing for the office, and get a more compact model for on the go...

 

Well this should take care of the cord sticking so far out on the right side...

I'm playing with it right now, and it seems that if I "jump start" it with them both plugged in I can unplug the DC from the right side and it stays up 100% with only the left side USB connected...

 

I noticed this too, but I also noticed a significant airflow loss. I have no way to measure this, it's just an observation by sticking my hand by the fan.

 

LMAO

I just unplugged everything and watched my GPU temps for another 10 minutes... absolutely no change whatsoever... the fans do nothing!

In fact I just put my laptop up on a game box and it is running 6C cooler than when sitting on the Cryo! I guess that solves that problem, RMA time!

 

Are you talking at min load or max load? I didn't get a notebook cooler for min load or to take everywhere. I got it for when I sit down and hammer the GPU in 8-10 hour MMO gaming sessions.

I'll test again later when I have time for a good chunk of gaming. I know what my temps are now on the cooler.. I'll try off later.

 

Big fan of the Cryo; when I had it first plugged in to the computer as noted above the fans would barely spin, and I've had the black screens on boot if the USB hub was connected without external power, but both issues vanished completely when I found an old power brick from a USB 1 hub I don't use anymore and plugged the cooler into that as the power source. Now turning the fans up high REALLY moves some air, so much I get "blow back" through the keyboard (!), the USB hub works perfectly, and no more black screens on boot. External power is the key... but I also love the product for the rise and tilt it gives the 7811, which are for me perfect. The NZXT is built like a tank, finely finished, and now that I've used it I can't imagine going without.

 

I think I'm going to try using external power. While I'm happy with current operation, cleaning it up so to speak wouldn't be bad.

I don't take the cooler anywhere, I only really use it when I sit down for long gaming sessions for peace of mind. So an extra cable doesn't bother me at all.

Any suggestions on an adapter for the cooler? I haven't found any specs for one yet.

 

I am talking about the maximum GPU load temps.

While playing WoW or looping the Crysis benchmark my GPU peaks around 76C under max load with the laptop sitting on my desk.

When I placed it onto the Cryo it dropped to around 66C, but with the fans on or off it doesn't make any difference. I know that they are moving at 100%, and it doesn't make a lick of difference.

Then when I just lift up the laptop by placing it on a game case my load temps top out at 60C... I've been watching it for almost a half hour and that its topped out.

I do like the angle the NZXT gives me, but paying $69.99 + shipping and I'm supposed to possibly buy an external adapter for another $5-10- is just way too much money for that... I have a better idea.



If you guys are happy with it then rock on, but I am not impressed.

 

Something like this should do the trick:

Wow Schmoof color coordinated ... Metrosexuals unite!

 

Metrosexual? LOL What do you think?

 

Underneath that rough exterior, I know there is a sweet smelling, color coordinated soul wearing a lavender thong.

 

What about the HD while using the box, does it ever approach 60c? I agree btw...it seems the cryo is placebo effect, however I think this has more to do with the vent placement on the P-7811.

 

I just read something very interesting.. check this out.. it's just a quote from wikipedia.

The USB specification provides a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines.[14] Initially, a device is only allowed to draw 100 mA. It may request more current from the upstream device in units of 2 mA up to a maximum of 500 mA.

I bet that has something to do with the power issues and that ramping up effect we were talking about to get the cooler going. Just a thought.

And as another thought though, what power do you think I should use for this cooler? 5v 9v? I can get an adapter with different plugs.. thats not the issue, just want to make sure the power being supplied is good.

 

well I have this cooler and I have no problem with both on the left side or one on the left and one on the right. What I do notice is that even ramped up to the max the airflow is seriously lacking. I might buy the AC adapter posted here. I mainly bought the cooler so I could use the laptop on my bed since I love to program and nap in the middle of it .

I actually had better temps when I used it on my table w/o the cooler but I bet I get better temps while I type this on my bed while I'm ready to nap

 

laptop coolers.... over rated and do no where near what they are suppose to. i have tried 10 different ones so far.

edit: coolers are better for beds/thick carpets or rugs/ very small work spaces. and they only work as well as the power settings on the computer will let them. (laptop cooler trick)

 

i agree. after reading the rave reviews about the zalman nc2000 i decided to get one. the only thing i noticed that was cooler was the hdd. Also, during 3dmark06 the laptop crashes when hooked up to the cooler. without the cooler, the laptop has not crashed during hours of gaming and stress testing. so i think it is safe to say that these coolers are using too much power that the power brick can output for both the laptop and the cooler. i bet there is a correlation between bsod/crashes with these sizzling power bricks. time to get the targus 180w, i guess.

 

Does the NZXT blow the air up? Or suck the air down?

 

Blows up. I have an external power supply and if I crank the fans to max I get warm air blowing up on my hands through the keyboard... sorta nice on chilly nights in Maine :yes: .

 

Reading Newegg reviews (always an adventure) seems to indicate that the fans can be "easily" made to blow either way. (This reviewer was of high tech level or at least high on something).

I like tallan's comment on air through the keyboard. Show that this cooler may not be just another pretty face. If I were in the market for a cooler, I would grab this one.

 

Can some give the specs (or better to say - current) of the fans? I believe you can easily find it on the fans. I need this in order to buy AC adaptor strong enough to feed these 120mm monsters

I've found - it's 0.41A. No wonder why USB power is not enough

 

that happened to me, but it fried the BIOS or something, my 7811 didnt post at all, whether i had the cryo plugged in with it or not. i had to send it back to gateway and they replaced the mobo, but this new one has a messed up gpu fan and it grinds when it goes to a high rpm and its quite annoying.
